Containing an application in an immersive non-windowed environment

ABSTRACT

Techniques are described herein that are capable of containing an application in an immersive non-windowed environment. For instance, the application may be configured for use in a windowed environment. Containing the application in the immersive non-windowed environment may involve selectively implementing functionality that is associated with the application based at least in part on whether the functionality is applicable to the immersive non-windowed environment. For example, when a request to implement functionality that is not applicable to the immersive non-windowed environment is received, functionality that is applicable to the immersive non-windowed environment may be implemented in lieu of the functionality that is not applicable to the immersive non-windowed environment. In another example, no action may be taken with regard to the request.

BACKGROUND

Over the past several decades, many applications (e.g., conventional desktop applications) have been configured for use in a windowed environment. A windowed environment is an environment in which applications are displayed in free-floating windows whose positioning is controlled by the applications that are displayed therein. For instance, the applications may be configured to call APIs that enable the applications to position themselves, spawn new windows that layer on top of their existing windows, etc. Accordingly, the windowed environment may have a z-order, which enables windows to be occluded by other windows.

Recent developments in the computer industry have led to applications that are configured for use in an immersive non-windowed environment in lieu of the traditional windowed environment. For instance, applications on devices such as tablet computers and personal digital assistants commonly are configured for use in the immersive non-windowed environment. An immersive non-windowed environment is an environment in which applications are not displayed in free-floating windows whose positioning is controlled by the applications that are displayed therein. Moreover, an immersive non-windowed environment traditionally does not have a z-order and therefore traditionally does not support occlusion of windows by other windows. In an immersive non-windowed environment, an application often is presented full-screen, meaning that the application consumes an entirety of the screen.

Windows® 8/8.1, which is developed and distributed by Microsoft Corporation, configures an entire desktop as an application, which may include all windows for the various other applications that are executed by a device. Accordingly, the application may enable windows to occlude other windows within the context of the application, even though occlusion is not applicable to the immersive non-windowed environment. However, enabling windows to occlude other windows in the context of the application may cause confusion for users.

SUMMARY

Various approaches are described herein for, among other things, containing an application (e.g., a computer application or a desktop computer application) in an immersive non-windowed environment. In accordance with these approaches, the application may be configured for use in a windowed environment. For instance, containing the application in the immersive non-windowed environment may involve selectively implementing functionality that is associated with the application based at least in part on whether the functionality is applicable to the immersive non-windowed environment. For example, when a request to implement functionality that is not applicable to the immersive non-windowed environment is received, functionality that is applicable to the immersive non-windowed environment may be implemented in lieu of the functionality that is not applicable to the immersive non-windowed environment. In another example, no action may be taken with regard to the request.

In a first example approach, a communication channel is established between an application and an operating system to broker window-related communications between the application and the operating system. A windowing policy is enforced via the communication channel in an immersive non-windowed environment using the window-related communications.

In a second example approach, APIs that are associated with an application are redefined from a first definition state to a second definition state based at least in part on the application being in an immersive non-windowed environment. The first definition state is characterized by the APIs defining window-based functionalities. The second definition state is characterized by the APIs defining immersive non-windowed functionalities. An API call for a designated API is received from the application. A first functionality of the window-based functionalities is defined by the designated API in the first state. A second functionality of the immersive non-windowed functionalities is defined by the designated API in the second state. The second functionality is implemented in lieu of the first functionality in response to receiving the API call.

II. Example Embodiments

Example embodiments described herein are capable of containing an application (e.g., a computer application or a desktop computer application) in an immersive non-windowed environment. In accordance with the example embodiments, the application may be configured for use in a windowed environment. For instance, containing the application in the immersive non-windowed environment may involve selectively implementing functionality that is associated with the application based at least in part on whether the functionality is applicable to the immersive non-windowed environment. For example, when a request to implement functionality that is not applicable to the immersive non-windowed environment is received, functionality that is applicable to the immersive non-windowed environment may be implemented in lieu of the functionality that is not applicable to the immersive non-windowed environment. In another example, no action may be taken with regard to the request.

Example techniques described herein have a variety of benefits as compared to conventional techniques for providing applications in an immersive non-windowed environment. For instance, the example techniques may enable an application that is configured to operate in a windowed environment to operate in a manner that is compatible with an immersive non-windowed environment. The example techniques may be capable of intercepting a request for functionality associated with the application that is not applicable to the immersive non-windowed environment, implement alternative functionality that is applicable to the immersive non-windowed environment in lieu of the requested functionality, block the request, block an instruction from an operating system that is provided in response to the request, convert the instruction from the operating system from a form that is not compatible with the immersive non-windowed environment to a form that is compatible with the immersive non-windowed environment, etc.

The example techniques may be capable of removing an application's authority to control its positioning (e.g., size, movement, and/or location on a screen). For instance, the authority may be given to a user of the application. Accordingly, the example techniques may be capable of ensuring that the user's instructions regarding positioning of the application are honored, rather than relying on goodwill of the application to honor the instructions.

The example techniques may substantially increase reliability and/or efficiency of a computing device with respect to executing an application, which is configured to operate in a windowed environment, in an immersive non-windowed environment. The example techniques may increase user interaction performance. For instance, such performance may be increased by requiring an application to comply with a user's instructions with regard to positioning of the application, not implementing functionality that is not applicable to the immersive no-windowed environment (e.g., windows occluding other windows), etc.

FIG. 1 is a block diagram of an example containment system 100 in accordance with an embodiment. Generally speaking, containment system 100 operates to provide information to users in response to requests (e.g., hypertext transfer protocol (HTTP) requests) that are received from the users. The information may include documents (e.g., Web pages, images, audio files, video files, etc.), output of executables, and/or any other suitable type of information. In accordance with example embodiments described herein, containment system 100 contains an application in an immersive non-windowed environment. For instance, containing the application in the immersive non-windowed environment may involve selectively implementing functionality that is associated with the application based at least in part on whether the functionality is applicable to the immersive non-windowed environment. Detail regarding techniques for containing an application in an immersive non-windowed environment is provided in the following discussion.

As shown in FIG. 1, containment system 100 includes a plurality of client devices 102A-102M, a network 104, and a plurality of machines 106A-106N. Communication among client devices 102A-102M and machines 106A-106N is carried out over network 104 using well-known network communication protocols. Network 104 may be a wide-area network (e.g., the Internet), a local area network (LAN), another type of network, or a combination thereof.

Client devices 102A-102M are processing systems that are capable of communicating with machines 106A-106N. An example of a processing system is a system that includes at least one processor that is capable of manipulating data in accordance with a set of instructions. For instance, a processing system may be a computer, a personal digital assistant, etc. Client devices 102A-102M are configured to provide requests to machines 106A-106N for requesting information stored on (or otherwise accessible via) machines 106A-106N. For instance, a user may initiate a request for executing a computer program (e.g., an application) using a client (e.g., a Web browser, Web crawler, or other type of client) deployed on a client device 102 that is owned by or otherwise accessible to the user. In accordance with some example embodiments, client devices 102A-102M are capable of accessing domains (e.g., Web sites) hosted by servers 104A-104N, so that client devices 102A-102M may access information that is available via the domains. Such domain may include Web pages, which may be provided as hypertext markup language (HTML) documents and objects (e.g., files) that are linked therein, for example.

Client devices 102A-102M may include any client-enabled system or device, including but not limited to a desktop computer, a laptop computer, a tablet computer, a personal digital assistant, a cellular telephone, a wearable device, or the like. It will be recognized that any one or more client devices 102A-102M may communicate with any one or more machines 106A-106N.

First client device 102A is shown to include containment logic 108 for illustrative purposes. Containment logic 108 is configured to contain an application in an immersive non-windowed environment. For example, containment logic 108 may establish a communication channel between the application and an operating system to broker window-related communications between the application and the operating system. Each of the application and the operating system may be executed by first client device 102A and/or one or more of machines 106A-106N. For instance, each of the application and the operating system (or server-side aspects thereof) may be implemented as a web-based service. In accordance with this example, containment logic 108 may enforce a windowing policy via the communication channel in the immersive non-windowed environment using the window-related communications. A windowing policy is a policy that defines how window-related communications are to be processed. Containment logic 108 may be incorporated at least partially (e.g., entirely (e.g., entirely) in the operating system, though the example embodiments is not limited in this respect.

In another example, containment logic 108 may redefine APIs that are associated with the application from a first definition state to a second definition state based at least in part on the application being in the immersive non-windowed environment. The first definition state is characterized by the APIs defining window-based functionalities. The second definition state is characterized by the APIs defining immersive non-windowed functionalities. In accordance with this example, a first functionality of the window-based functionalities is defined by the designated API in the first state, and a second functionality of the immersive non-windowed functionalities is defined by the designated API in the second state. In further accordance with this example, containment logic 108 may implement the second functionality in lieu of the first functionality in response to receipt of an API call for an API from the application.

Example techniques for containing an application in an immersive non-windowed environment are discussed in greater detail below with reference to FIGS. 2-10.

Machines 106A-106N are processing systems that are capable of communicating with client devices 102A-102M. Machines 106A-106N are configured to execute computer programs that provide information to users in response to receiving requests from the users. For example, the information may include documents (e.g., Web pages, images, audio files, video files, etc.), output of executables, or any other suitable type of information. In accordance with some example embodiments, machines 106A-106N are configured to host respective Web sites, so that the Web sites are accessible to users of containment system 100.

Containment logic 108 is shown to be incorporated in first client device 102A for illustrative purposes and is not intended to be limiting. It will be recognized that at least a portion (e.g., all) of containment logic 108 may be external to first client device 102A. For example, at least a portion of containment logic 108 may be incorporated in any one or more of the machines 106A-106N. In accordance with this example, client-side aspects of containment logic 108 may be incorporated in client device 102A, and server-side aspects of containment logic 108 may be incorporated in one or more of the machines 106A-106N.

Containment logic 108 may be implemented in various ways to contain an application in an immersive non-windowed environment, including being implemented in hardware, software, firmware, or any combination thereof. For example, containment logic 108 may be implemented as computer program code configured to be executed in one or more processors. In another example, containment logic 108 may be implemented as hardware logic/electrical circuitry. For instance, containment logic 108 may be implemented in a field-programmable gate array (FPGA), an application-specific integrated circuit (ASIC), an application-specific standard product (ASSP), a system-on-a-chip system (SoC), a complex programmable logic device (CPLD), etc. Each SoC may include an integrated circuit chip that includes one or more of a processor (e.g., a microcontroller, microprocessor, digital signal processor (DSP), etc.), memory, one or more communication interfaces, and/or further circuits and/or embedded firmware to perform its functions.

It will be recognized that any one or more of client devices 102A-102M and/or any one or more of machines 106A-106N may be implemented as a virtual machine, though the scope of the example embodiments is not limited in this respect.

FIG. 2 depicts a flowchart 200 of an example method for containing an application in an immersive non-windowed environment in accordance with an embodiment. Flowchart 200 may be performed by any one or more of client devices 102A-102M and/or any one or more of machines 106A-106N shown in FIG. 1, for example. For illustrative purposes, flowchart 200 is described with respect to a computing system 300 shown in FIG. 3. As shown in FIG. 3, computing system 300 includes an operating system 302, containment logic 304, an application 306, a store 308, and a screen 328. Containment logic 304 includes establishment logic 310 and enforcement logic 312. Further structural and operational embodiments will be apparent to persons skilled in the relevant art(s) based on the discussion regarding flowchart 200.

As shown in FIG. 2, the method of flowchart 200 begins at step 202. In step 202, a communication channel is established between the application and an operating system to broker window-related communications between the application and the operating system. In an example implementation, establishment logic 310 establishes a communication channel 322 between the application 306 and the operating system 302, as depicted by arrow 324, to broker window-related communications between the application 306 and the operating system 302. Accordingly, establishment logic 310 may enable instructions to be provided to the application and/or requests to be received from the application.

For example, establishment logic 310 may be implemented as (or incorporated into) a window manager. A window manager is system software that is configured to control positioning and/or appearance of windows in a windowed environment. For instance, the window manager may be configured to enable a user of computing system 300 to open, close, minimize, maximize, move, and/or resize windows that are running on computing device 300.

At step 204, a windowing policy is enforced via the communication channel in the immersive non-windowed environment using the window-related communications. A windowing policy is a policy that defines how window-related communications are to be processed. For example, the windowing policy may include rules that define how windows may be manipulated. Accordingly, changing from one windowing policy to another windowing policy may require re-mapping of the rules. In an example implementation, enforcement logic 312 enforces a windowing policy 320 via the communication channel 322 in the immersive non-windowed environment using the window-related communications. For example, store 308 may be configured to store the windowing policy 320. Store 308 may be further configured to provide the windowing policy 320 and/or information regarding the windowing policy 320 in response to queries that request the windowing policy 320 and/or information regarding the windowing policy 320. Store 308 may be any suitable type of store. One type of store is a database. For instance, store 308 may be a relational database, an entity-relationship database, an object database, an object relational database, an extensible markup language (XML) database, etc. In accordance with this example, enforcement logic 312 may retrieve the windowing policy 320 from store 308. In accordance with this example, enforcement logic 312 may review the windowing policy 320 to determine provisions therein, which are to be enforced.

For example, enforcement logic 312 may be implemented as (or incorporated into) a shell. A shell is a user interface that is configured to access services of an operating system (e.g., operating system 302). For instance, the shell may use a command-line interface (CLI) or a graphical user interface (GUI) to provide access to the services of the operating system to a user of computing system 300.

In an example embodiment, step 204 includes issuing an instruction to the application in response to receiving an event from the application. For instance, enforcement logic 312 may issue the instruction to the application 306 in response to receiving the event from the application 306. For example, the event may be an API call. In accordance with this embodiment, the operating system 302 may include a positioner. The positioner may be configured to monitor communications to identify events from establishment logic 310 that are received from the application 306. For instance, an event may indicate that the application 306 intends to position itself (e.g., a window that includes the application 306) on screen 328. The application may intend to position itself by changing its size and/or location on screen 328 and/or by opening a new window in which the application 306 is to be displayed on screen 328. The positioner (or one or more portions thereof) may be included in a window manager and/or a shell, though the scope of the example embodiments is not limited in this respect.

In a first aspect of this embodiment, the instruction may require the application to position a window at a designated location of a screen in the immersive non-windowed environment. For example, the instruction may require the application 306 to position the window at the designated location of screen 328. In accordance with this example, the instruction may require the application 306 to position the window at the designated location of screen 328 in response to the event indicating that the application 306 intended to change its location on screen 328 (e.g., to a location that is different from the designated location).

In a second aspect of this embodiment, the instruction may require the application to provide a window having a designated size on a screen in the immersive non-windowed environment. For example, the instruction may require the application 306 to provide the window having the designated size on screen 328. In accordance with this example, the instruction may require the application 306 to provide the window having the designated size on screen 328 in response to the event indicating that the application 306 intended to change its size on screen 328 (e.g., to a size that is different from the designated size) or in response to the event indicating that the application 306 intended to open a new window in which the application 306 was to be displayed on screen 328.

In another example embodiment, step 204 includes intercepting and blocking an instruction that is intended to be provided from the operating system to the application based on the instruction not being applicable to the immersive non-windowed environment. In an example embodiment, enforcement logic 312 is configured to intercept and block the instruction that is intended to be provided from the operating system 302 to the application 306 based on the instruction not being applicable to the immersive non-windowed environment. For instance, the instruction may indicate that the application 306 is to be restored from a title bar.

In some example embodiments, one or more steps 202 and/or 204 of flowchart 200 may not be performed. Moreover, steps in addition to or in lieu of steps 202 and/or 204 may be performed.

FIGS. 4, 5A, 5B, and 6 depict flowcharts 400, 500, 550, and 600 of example methods for enforcing a windowing policy in accordance with embodiments. For instance, the methods of flowcharts 400, 500, 550, and 600 may be example implementations of step 204 shown in FIG. 2. Flowcharts 400, 500, 550, and 600 are described accordingly in the following discussion. Flowcharts 400, 500, 550, and 600 may be performed by enforcement logic 312 shown in FIG. 3, for example. For illustrative purposes, flowcharts 500, 550, and 600 are described with respect to enforcement logic 700 shown in FIG. 7, which is an example implementation of enforcement logic 312 of FIG. 3. Enforcement logic 700 includes conversion logic 702, interception logic 704, and provision logic 706. Further structural and operational embodiments will be apparent to persons skilled in the relevant art(s) based on the discussion regarding flowcharts 400, 500, 550, and 600.

As shown in FIG. 4, the method of flowchart 400 begins at step 402. In step 402, a determination is made whether a specified functionality of the application is applicable to the immersive non-windowed environment. If the specified functionality is applicable to the immersive non-windowed environment, flow continues to step 404. Otherwise, flow continues to step 406. In an example implementation, the operating system 302 determines whether the specified functionality of the application 306 is applicable to the immersive non-windowed environment. The operating system 302 may generate an instruction 316 in response to determining whether the specified functionality of the application 306 is applicable to the immersive non-windowed environment. The instruction 316 may indicate that the specified functionality is to be implemented in response to the specified functionality being applicable to the immersive non-windowed environment. The instruction 316 may indicate that the specified functionality is not to be implemented in response to the specified functionality not being applicable to the immersive non-windowed environment.

In an aspect of this implementation, the operating system 302 may receive an event (e.g., an API call) from the application 302. The event may indicate that the specified functionality is to be implemented. For instance, the event may request implementation of the specified functionality. In accordance with this example, the operating system may determine whether the specified functionality is applicable to the immersive non-windowed environment in response to receipt of the event.

In another aspect of this implementation, the operating system 302 may provide an inquiry 314 to the application 306. The inquiry 314 may request an indication of functionality that is associated with the application 306. In accordance with this example, the application 306 may provide functionality information 318 to the operating system 302 in response to receipt of the inquiry 314. The functionality information may indicate that the specified functionality is associated with the application 306. The operating system 302 may determine whether the specified functionality is applicable to the immersive non-windowed environment in response to receipt of the functionality information 318.

At step 404, the application is instructed to implement (e.g., perform) the specified functionality. For instance, the application may be instructed to implement the specified functionality based on the specified functionality being applicable to the immersive non-windowed environment. In an example implementation, the operating system 302 instructs the application 306 to implement the specified functionality. In accordance with this implementation, the operating system 302 may generate the instruction 316 to specify that the specified functionality is to be implemented based on a determination that the specified functionality is applicable to the immersive non-windowed environment. In further accordance with this implementation, the operating system 302 may provide the instruction 316 to the application 306.

At step 406, the application is not instructed to implement the specified functionality. For instance, the application may not be instructed to implement the specified functionality based on the specified functionality not being applicable to the immersive non-windowed environment. In an example implementation, the operating system 302 does not instruct the application 306 to implement the specified functionality. For instance, the operating system 302 may not provide the instruction 316 based on a determination that the specified functionality is not applicable to the immersive non-windowed environment.

It will be recognized that computing system 300 may not include one or more of operating system 302, containment logic 304, application 306, store 308, establishment logic 310, enforcement logic 312, and/or screen 328. Furthermore, computing system 300 may include components in addition to or in lieu of operating system 302, containment logic 304, application 306, store 308, establishment logic 310, enforcement logic 312, and/or screen 328.

As shown in FIG. 5A, the method of flowchart 500 begins at step 502. In step 502, an instruction that is intended to be provided from the operating system to the application is intercepted. In an example implementation, interception logic 704 intercepts an instruction 708 that is intended to be provided from the operating system (e.g., operating system 302) to the application (e.g., application 306). In accordance with this implementation, interception logic 708 may determine whether the instruction 708 is compatible with the immersive non-windowed environment. In further accordance with this implementation, interception logic 704 may forward the instruction 708 to conversion logic 702 in response to a determination that the instruction 708 is not compatible with the immersive non-windowed environment. For example, the instruction 708 may indicate that the application (e.g., a window that includes the application) is to be minimized, maximized, restored, moved, and/or resized.

At step 504, the instruction is converted from a first form that is not compatible with the immersive non-windowed environment to a second form that is compatible with the immersive non-windowed environment. In an example implementation, conversion logic 702 converts the instruction 708 from a first form that is not compatible with the immersive non-windowed environment to a second form that is compatible with the immersive non-windowed environment to provide a converted instruction 712.

For example, the first form may be configured to control a move-size loop that is associated with the application. A move-size loop defines how an operating system communicates with an application when the application is being dragged or re-sized by a user. Accordingly, the move-size loop may provide messages about moving and/or sizing that the application may continually process in a looping fashion. In accordance with this example, the second form may be configured to control positioning of the application outside a context of the move-size loop. In an aspect of this example, the second form may be configured to block the move-size loop.

In another aspect of this example, the second form may be configured to position thumbnail(s) that represent the application in lieu of the application on a screen until a completion indicator (e.g., deselection of the thumbnail(s)) is received. For instance, the thumbnail(s) may be moved independently from a window that is associated with the application. In accordance with this aspect, the completion indicator may indicate that the thumbnail(s) are located at a location on the screen at which the application is to be positioned. In accordance with this aspect, the application may be positioned at the location of the thumbnail(s) in response to receipt of the completion indicator. For instance, the application may replace the thumbnail(s) at the location on the screen. An animation may be performed to transition the application from an initial location on the screen to the location at which the thumbnail(s) are positioned, though the scope of the example embodiments is not limited in this respect.

In yet another aspect of this example, the second form may be configured to cause other applications to be repositioned (e.g., resized or relocated) to accommodate positioning of the application on a screen. For instance, the other applications may be repositioned (e.g., as the thumbnail(s) are positioned) so that the application and the other applications do not overlap on the screen (e.g., at a time instance at which positioning of the application is complete). In one implementation, if a thumbnail of the application is dragged to overlap with a target application, the second form may cause the application that was dragged and the target application to switch places on the screen. In accordance with this implementation, the application (or an icon associated therewith) may switch places with each successive application (or an icon associated therewith) along a row of applications (or icons associated therewith) as the application is dragged along the row.

As illustrated by this example, the second form may enable enforcement logic 312 to control user experience policy and/or windowing policy with regard to the application.

As shown in FIG. 5B, the method of flowchart 550 begins at step 552. In step 552, a first form of an instruction that is received from a user of the computing system and that is intended to be provided to the application is intercepted. The first form is configured to control a move-size loop that is associated with the application. In an example implementation, interception logic 704 intercepts a first form of an instruction 708 that is received from a user of the computing system (e.g., computing system 300) and that is intended to be provided to the application (e.g., application 306). In accordance with this implementation, interception logic 708 may determine whether the instruction 708 is compatible with the immersive non-windowed environment. For instance, interception logic 708 may determine that the instruction 708 is not compatible with the immersive non-windowed environment based on the instruction 708 being in the first form, which is configured to control the move-size loop that is associated with the application. In further accordance with this implementation, interception logic 704 may forward the instruction 708 to conversion logic 702 in response to a determination that the instruction 708 is not compatible with the immersive non-windowed environment.

At step 554, the first form of the instruction is converted to a second form of the instruction that is configured to control positioning of the application outside a context of the move-size loop. In an example implementation, conversion logic 702 converts the first form of the instruction 708 to a second from of the instruction 708 that is configured to control positioning of the application outside the context of the move-size loop to provide the converted instruction 712.

At step 556, the second form of the instruction is provided to the application. For example, the second form of the instruction may be provided in lieu of the first form of the instruction to the application. In another example, the instruction may pertain to sizing the application, moving the application, or positioning the application at a specified location on a screen in the immersive non-windowed environment. In an example implementation, conversion logic 702 provides the second form of the instruction 708 to the application.

In an example embodiment, the second form of the instruction is configured to cause a thumbnail, which represents the desktop computer application, in lieu of the desktop computer application to be positioned on a screen of the computing system until a completion indicator is received. In accordance with this embodiment, the completion indicator indicates that the thumbnail is located at a specified location on the screen at which the desktop computer application is to be positioned. In further accordance with this embodiment, the second form of the instruction is configured to cause the desktop computer application to be positioned at the specified location in response to receipt of the completion indicator.

In an aspect of this embodiment, the second form of the instruction is configured to cause the desktop computer application and a target application to switch places on the screen in response to the thumbnail overlapping the target application on the screen when the completion indicator is received.

In another example embodiment, the second form of the instruction is configured to cause one or more other computer applications to be repositioned to accommodate positioning of the desktop computer application on a screen of the computing system.

As shown in FIG. 6, the method of flowchart 600 begins at step 602. In step 602, an API call that is issued by the application is intercepted. In an example implementation, interception logic 704 intercepts an API call 710 that is issued by the application (application 306). In accordance with this implementation, interception logic 704 may forward the API call 710 to provision logic 706.

At step 604, a second response that corresponds to the immersive non-windowed environment rather than a first response that corresponds to a windowed environment is provided in response to the API call. In an example implementation, provision logic 706 may provide a response 714 that corresponds to the immersive non-windowed environment rather than an alternative response that corresponds to the windowed environment in response to the API call 710. For example, provision logic 706 may determine that the alternative response corresponds to the windowed environment. In accordance with this example, provision logic 706 may provide the response 714 in response to a determination that the alternative response corresponds to the windowed environment. For example, the alternative response may indicate that a dialog box is to be provided on the screen 328. In one aspect of this example, the dialog box may indicate that the application is to be closed. In another aspect the dialog box may provide an option to save a file. In yet another aspect, the dialog box may provide an option to open a file and/or to select a file to be opened from a plurality of files.

It will be recognized that enforcement logic 700 may not include one or more of conversion logic 702, interception logic 704, and/or provision logic 706. Furthermore, enforcement logic 700 may include components in addition to or in lieu of conversion logic 702, interception logic 704, and/or provision logic 706.

FIG. 8 depicts a flowchart 800 of an example method for controlling an application in an immersive non-windowed environment in accordance with an embodiment. Flowchart 800 may be performed by any one or more of client devices 102A-102M and/or any one or more of machines 106A-106N shown in FIG. 1, for example. For illustrative purposes, flowchart 800 is described with respect to a computing system 900 shown in FIG. 9. As shown in FIG. 9, computing system 900 includes an operating system 902, containment logic 904, and a screen 908. Containment logic 904 includes definition logic 910 and implementation logic 912. Screen 908 is shown to display an application 906. Some example embodiments are described with respect to implementation logic 1000 of FIG. 10, which is an example implementation of implementation logic 912 of FIG. 9. Implementation logic 1000 includes interception logic 1002 and conversion logic 1004. Further structural and operational embodiments will be apparent to persons skilled in the relevant art(s) based on the discussion regarding flowchart 900.

As shown in FIG. 8, the method of flowchart 800 begins at step 802. In step 802, APIs that are associated with the application are redefined from a first definition state to a second definition state based at least in part on the application being in the immersive non-windowed environment. The first definition state is characterized by the APIs defining a plurality of window-based functionalities. A window-based functionality is a functionality that is applicable to a windowed environment and that is not applicable to the immersive non-windowed environment. The second definition state is characterized by the APIs defining a plurality of immersive non-windowed functionalities. An immersive non-windowed functionality is a functionality that is applicable to the immersive non-windowed environment. In an example implementation, definition logic 910 redefines APIs 914 that are associated with the application 906 from the first definition state to the second definition state based at least in part on the application 906 being in the non-windowed environment to provide redefined APIs 922. For example, definition logic 910 may redefine the APIs 914 that are associated with the application 906 in response to environment information 916. In accordance with this example, the environment information 916 may indicate (e.g., specify) that the application 906 is in the non-windowed environment. In accordance with this implementation, the first definition state is characterized by the APIs 914 defining a plurality of window-based functionalities. In further accordance with this implementation, the second definition state is characterized by the APIs 914 defining a plurality of immersive non-windowed functionalities.

In an example embodiment, step 802 includes taking authority to control positioning of the application on a screen of a computing system from the application. Examples of positioning an application include but are not limited to sizing (e.g., resizing) a window in which the application is displayed (e.g., selecting a size of the window from a plurality of potential sizes), moving a window in which the application is displayed from a first location on a screen to a second location on the screen that is different from the first location (e.g., selecting the second location from a plurality of potential locations on the screen), and placing a window in which the application is displayed at a location on a screen (e.g., selecting the location from a plurality of potential locations on the screen). For instance, definition logic 910 may take the authority to control the positioning of the application 906 on screen 908 from the application 906. In accordance with this embodiment, step 802 further includes providing the authority to a user of the application. For instance, definition logic 910 may provide the authority to the user of computing system 900.

In another example embodiment, step 802 includes determining whether each functionality of a corpus of functionalities is applicable to the immersive non-windowed environment. The corpus of functionalities includes the plurality of window-based functionalities, which are not applicable to the immersive non-windowed environment, and one or more other functionalities, which are applicable to the immersive non-windowed environment. For instance, definition logic 910 may determine whether each functionality of the corpus of functionalities is applicable to the immersive non-windowed environment. In accordance with this example, step 902 further includes for each functionality of the corpus of functionalities, if the respective functionality is applicable to the immersive non-windowed environment, not redefining the API that defines the respective functionality from the first definition state to the second definition state, based at least in part on the respective functionality being applicable to the immersive non-windowed environment. For instance, definition logic 910 may not redefine the API that defines the respective functionality if the respective functionality is applicable to the immersive non-windowed environment. APIs that are not redefined may be referred to cumulatively as non-redefined APIs 924. In further accordance with this example, step 802 further includes for each functionality of the corpus of functionalities, if the respective functionality is not applicable to the immersive non-windowed environment, redefining the API that defines the respective functionality from the first definition state to the second definition state, based at least in part on the respective functionality not being applicable to the immersive non-windowed environment. For instance, definition logic 910 may redefine the API that defines the respective functionality if the respective functionality is not applicable to the immersive non-windowed environment. APIs that are redefined may be referred to cumulatively as redefined APIs 924.

At step 804, an API call for a designated API is received from the application. In an example implementation, implementation logic 912 receives an API call 920 for the designated API from the application 906.

At step 806, a second functionality of the plurality of immersive non-windowed functionalities, which is defined by the designated API in the second state, is implemented in lieu of a first functionality of the plurality of window-based functionalities, which is defined by the designated API in the first state, in response to receiving the API call. In an example implementation, implementation logic 912 implements the second functionality in lieu of the first functionality in response to receipt of the API call 920.

In an example embodiment, step 806 includes issuing an instruction to the application in response to receiving the API call. For instance, implementation logic 912 may issue an instruction 926 to the application 906 in response to receiving the API call 920. In accordance with this embodiment, the instruction requires the application to position a window at a designated location on a screen of the computing system in the immersive non-windowed environment. For instance, the instruction 926 may require the application 906 to position the window at a designated location on the screen 908 in the immersive non-windowed environment.

In another example embodiment, step 806 includes issuing an instruction to the application in response to receiving the API call. For instance, implementation logic 912 may issue the instruction 926 to the application 906 in response to receiving the API call 920. In accordance with this embodiment, the instruction requires the application to provide a window having a designated size on a screen of the computing system in the immersive non-windowed environment. For instance, the instruction 926 may require the application 906 to provide a window having a designated size on screen 908 in the immersive non-windowed environment.

In some example embodiments, one or more steps 802, 804, and/or 806 of flowchart 800 may not be performed. Moreover, steps in addition to or in lieu of steps 802, 804, and/or 806 may be performed. For instance, in an example embodiment, the method of flowchart 800 further includes intercepting and blocking an instruction that is intended to be provided from an operating system of the computing system to the application based on the instruction not being applicable to the immersive non-windowed environment. For instance, interception logic 1002 of FIG. 10 may intercept and block the instruction that is intended to be provided from the operating system (e.g., operating system 902) to the application (e.g., application 906) based on the instruction not being applicable to the immersive non-windowed environment.

In another example embodiment, the method of flowchart 800 further includes intercepting an instruction that is intended to be provided from an operating system of the computing system to the application. For instance, interception logic 1002 may intercept the instruction that is intended to be provided from the operating system (e.g., operating system 902) to the application (e.g., application 906). In accordance with this embodiment, the method of flowchart 800 further includes converting the instruction from a first form that is not compatible with the immersive non-windowed environment to a second form that is compatible with the immersive non-windowed environment. For instance, conversion logic 1004 may convert the instruction from the first form to the second form.

Each of definition logic 910 and implementation logic 912 (or portion(s) thereof) may be incorporated in a window manager and/or a shell. For instance, the shell may redefine the APIs that are associated with the application at step 802. The window manager may receive the API call for the designated API at step 804. For example, the API call may request implementation of the first functionality. In accordance with this example, the window manager may provide an indicator to the shell in response to receiving the API call for the designated API. The indicator may indicate that implementation of the first functionality is requested. The shell may implement the second functionality in lieu of the first functionality in response to receipt of the indicator.

It will be recognized that computing system 900 may not include one or more of operating system 902, containment logic 904, application 906, screen 908, definition logic 910, and/or implementation logic 912. Furthermore, computing system 900 may include components in addition to or in lieu of operating system 902, containment logic 904, application 906, screen 908, definition logic 910, and/or implementation logic 912.
